D Type Impulse Current Test Systems - Chinaprice: contact company for price
The D type impulse current test systems are specially designed to generate impulse current of exponential shapes. The system can be designed in various ways for meeting customers’ requirements. The very user- friendly control unit can be expanded with a standard interface so that the tests can be controlled from a host computer.
The test object includes the below electrical apparatus:
SPD ( surge protective device)
Varistor, GDT, TVS
Other lightning protection device
IEC60060- 1, IEC60060- 2, IEC 61643- 11, UL1449, NFC 17- 102, GB18802.1, GB/ T18802.21 and other national standards
Advantages and Features
( 1) Stable structure and well- designed layout
( 2) Low inductance and average current in every capacitor
( 3) High charging voltage up to 200kV and the total energy up to 200kJ and more
( 4) Reliable and precisely controlled triggering unit by power pulse
( 5) Protective earthing system for safety
( 6) Shape resistors designed for low inductance and connected by easy joint
( 7) Specially designed circuit available for different shapes.
( 8) Easy operation with the console based on PLC module.
( 9) Special solutions to customer’s problem and special requirement
The impulse capacitors are charged through the HV DC charging unit. Charging time and charging voltage can be set in advance through the touch screen on the control unit. Once the charging voltage has been reached, the trigger sphere initiates the firing of the spark gap. The voltage divider and current sensor ( pearson coil) reduce the measuring signals to values that the measurement system requires.
The test system includes the following main components:
HV charging unit
Impulse current generator
Central spark gap
Housing of test object
Automatic earthing system
Automatic control system
AC/ DC power source for operating duty test
Coupling/ decoupling unit
Current shunt/ Pearson coil
Residual voltage divider
